Cho, Yeon Seok published the artcileNovel Phosphonium Chloride-Catalyzed Dehydrohalogenative Si-C Coupling Reaction of Alkyl Halides with Trichlorosilane, Application of Dichloro(hexyl)(methyl)silane, the publication is Journal of the American Chemical Society (2001), 123(23), 5584-5585, database is CAplus and MEDLINE.

The authors describe a novel catalytic approach to the coupling of both activated and nonactivated alkyl halides with both trichlorosilane and methyldichlorosilane using phosphonium salts as the catalysts. This synthetic approach will now enable the efficient, high-yield synthesis of a wide range of functionalized organosilicon compounds that were previously unavailable by simple means. Thus, RCl (R = CH₂C₆H₄X-p, X = H, F, MeO; CH₂HC:CHX, X = H, (Z)-Me; n-C_nH_2n+1, n = 6, 8, 12, 18; TMS(CH₂)_n, n = 1, 3) when coupled with HSiCl₃ in presence catalytic amounts of phosphonium salts [R¹₄P]Cl (R¹₄ = Bu₄, (PhCH₂)Bu₃) gave RSiCl₃ (R = same as above) in 72-96% yields. The extension of the coupling reaction to other alkyl halides such as secondary and tertiary alkyl halides is currently being studied.

Pan, Yong published the artcilePredicting the Net Heat of Combustion of Organosilicon Compounds from Molecular Structures, Application In Synthesis of 14799-94-1, the publication is Industrial & Engineering Chemistry Research (2012), 51(40), 13274-13281, database is CAplus.

The net heat of combustion is a most important property of flammable substances which can be used to estimate potential fire hazards of chems. once they ignite and burn. This work proposed a quant. structure-property relationship model to predict the net heat of combustion of 308 organosilicon compounds knowing only their mol. structures. Various types of mol. descriptors (topol., charge, geometry) were calculated to represent the organosilicon compound mol. structures. A genetic algorithm in conjunction with multiple linear regression was used to select an optimal descriptor subset which significantly contributed to the overall net heat of combustion property. The best resultant model was a 3-variable, multi-linear model, with root-mean-square and average absolute errors for the external test set of 176.8 and 111.2 kJ/mol, resp. The model was also validated to check its stability and predictive capability. Results showed this model was a valid, predictive model, and provides a new way to predict the net heat of combustion of organosilicon compounds for engineering applications.

Pan, Yong published the artcileA novel method for predicting the flash points of organosilicon compounds from molecular structures, Application of Dichloro(hexyl)(methyl)silane, the publication is Fire and Materials (2013), 37(2), 130-139, database is CAplus.

A quant. structure-property relationship (QSPR) study was performed to develop math. models to predict the flash point (FP) of organosilicon compounds from their mol. structures. Various types of mol. descriptors were calculated to represent the organosilicon compound mol. structures, e.g., topol., charge, and geometric descriptors. A genetic algorithm in conjunction with multiple linear regression (GA-MLR) was used to a select an optimal subset of descriptors which significantly contribute to overall FP properties. The model providing the best results was a 5-variable, multi-linear model, which displayed high prediction ability when obtained root mean square and average absolute errors for the external test set were 14.11 and 11.1° K, resp. The model was further compared with other previously published methods. Results indicated the superiority of the developed model, showing it can effectively predict organosilicon compound FP with only mol. structure knowledge. This study provides a new method to predict organosilicon compound FP for engineering fields. Copyright © 2012 John Wiley & Sons, Ltd.

Study of the hydrolysis reaction of higher alkylmethyl-dichlorosilanes shows that this reaction results in the formation of a mixture of cyclic and linear compounds Hydrolysis in HCl products only cyclic compounds, which can be vacuum distilled Condensation of the hydrolysis products of the higher alkyl-methyldichlorosilanes results in formation of a mixture of 6-, 8-, and 10-membered dialkyl cyclosiloxanes. In the chlorination of the dialkyl α,ω-dihydroxysiloxanes in the hydrolysis products of the (higher alkyl)methyldichlorosilanes, OH groups are replaced by Cl atoms.

Shen, Qionghua published the artcileSynthesis, Characterization, and Glass Transitions of Some Asymmetrically Substituted Poly(siloxanes), Safety of Dichloro(hexyl)(methyl)silane, the publication is Macromolecules (1997), 30(18), 5485-5489, database is CAplus.

A homologous series of poly(n-alkylmethylsiloxanes), [SiMe(R)O]_n, were prepared by cationic ring-opening polymerization (ROP) of cyclotrisiloxanes containing n-alkyl substituents, such as C₂H₅, n-C₃H₇, n-C₄H₉, n-C₅H₁₁, and n-C₆H₁₃, on the Si. The resultant polymers were characterized by NMR, GPC, and DSC measurements. All of these asym. substituted polymers were obtained in high mol. weight form and were found to have an atactic configuration. Their glass transitions were found to increase smoothly from Et to n-hexyl (i.e., -139, -120, -115, -111.9, and -108 °C, for Et to n-hexyl, resp.). These T_gs are much lower than those of the corresponding polyolefins, [C(H)(R)CH₂]_n. Moreover, in the case of these polyolefins, the T_gs decrease continuously from R = Me to n-hexyl. The calculated T_gs for the polysiloxanes that were obtained by using published empirical equations show the same general trend as the exptl. values.

Reaction of 1-hexene with MeCl2SiH in the presence of (Ph3P)2Pt(C2H4) (I) gave n-C6H13Si-MeCl2 in quant. yield via the intermediacy of (Ph3P)2PtH(SiMeCl2). In the absence of olefin, (Ph3P)2Pt(SiMeCl2)2 was isolated. I and HSiCl3 gave only (Ph3P)2Pt(SiCl3)2. Hydrosilylation of 1-hexene and Me3SiCH:CH2 was catalyzed by the complexes of I with (EtO)2MeSiH, Me2ClSiH, Me3SiH, or Me3EtSiH; the stability of such complexes decreased in the order SiCl3 > SiMeCl2 > SiMe3. I, MeCl2SiH, and 1,3-butadiene gave 1,2-, 1,4-, and dihydrosilylation products, but diaddn. was favored with isoprene.

Kang, Seung-Hyun published the artcilePhosphonium Chloride-Catalyzed Dehydrochlorinative Coupling Reactions of Alkyl Halides with Hydridochlorosilanes, Name: Dichloro(hexyl)(methyl)silane, the publication is Organometallics (2003), 22(3), 529-534, database is CAplus.

The dehydrochlorinative Si-C coupling reactions of various primary and secondary alkyl chlorides with hydridochlorosilanes in the presence of tetrabutylphosphonium chloride as catalyst gave the coupling products with elimination of HCl as a gas. For example, RCl (R = CH₂C₆H₄X-p; X = H, Cl, F, Me, MeO), when coupled with HSiCl₃ in the presence of catalytic amounts of phosphonium salts [Bu₄Y]Z (Y = P, N; Z = Cl, Br, I) gave RSiCl₃ (R = same as above) in 80-96% yields. Coupling reactions of activated alkyl chlorides such as benzyl chlorides proceeded at 130°, while unactivated organic chlorides such as silylalkyl chlorides and secondary alkyl chlorides required higher reaction temperatures of 150 or 170° and longer reaction times. Primary alkyl chlorides reacted with trichlorosilane (1) to give coupling products in good to excellent yields, but secondary alkyl chlorides reacted at a slower rate and gave lower yields of products. Coupling reactions with methyldichlorosilane instead of 1 proceeded at slower rates and gave lower yields of products.
